The styled letters are Unicode characters, so they paste into any app. Screen readers may read them badly and search will not match them. Keep them for a few words, not whole posts, and not for hashtags, links or @mentions.

Good to know

  • Only the first line or two of a caption show over the video before "more".
  • The styled letters are Unicode characters, not real formatting. Screen readers may read them badly and search does not match them, so use them sparingly.
  • Letters other than A to Z and digits are left as they are, so accented letters and non-Latin scripts are not styled.

Questions

Can I use bold or italic in a TikTok caption?

TikTok has no formatting buttons. Styled Unicode letters paste into captions and comments. Keep hashtags in plain text so they stay clickable.

How long can a caption be?

Up to 4,000 characters at the time of writing, but only the first line or two show before "more", so lead with the point.

Is my text sent to a server?

No. The styling runs in your browser and nothing is uploaded or saved.
